Strange that this was the case when the old APO-Televid 62 was done the 'right' way?
Not really. The Apo-Televid 77 and the Televid 77 came onto the market in 1994 or 1995. Can't remember the exact year. It was the first scope Leica ever made. The old Apo-Televid 62 appeared years later. Seems like Leica learned something in the meantime.
BTW, I took the Apo-Televid on a trip to Eastern Finland and Varanger in 1995. Nice trip actually, there were for instance still Yellow-browed Buntings breeding in Finland at the time, near the Russian border. After that trip I got in touch with Leica to suggest the filter threads on the hood were a stupid idea. Never got a reply from Leica. I also suggested they might want to make a smaller and lighter scope. Carrying the Apo-Televid up Valtavaara Ridge for Red-flanked Bluetail wasn't fun at all. The reply I got was that nobody would be interested in a smaller scope. Nobody.
When Zeiss started making the first big Diascopes repeated itself. I got the same reply from Zeiss when I told them there was definitely a market for a smaller scope. No, never. It also took them a few years before they came around.
That's why I switched to Nikon Fieldscopes when I had a chance to get an EDIIA and an ED78 at reasonable prices.
